lips_score: Lung Injury Prediction Score (LIPS)

Description

Calculates the Lung Injury Prediction Score (LIPS) to identify patients at high risk for developing Acute Lung Injury (ALI) or Acute Respiratory Distress Syndrome (ARDS). The score sums points for predisposing conditions (like shock, aspiration, sepsis) and risk modifiers (like alcohol use, obesity, and vital signs). A score of 4 or greater typically indicates high risk.

Usage

lips_score(shock, aspiration, sepsis, pneumonia, high_risk_surgery,
           high_risk_trauma, alcohol_abuse, obesity_bmi_gt_30, hypoalbuminemia,
           chemotherapy, fio2_gt_0_35_or_4l, tachypnea_rr_gt_30, spo2_lt_95,
           acidosis_ph_lt_7_35, diabetes_mellitus)

Value

A list containing:

LIPS_Score

The calculated total score (Range -1 to >20).

Risk_Category

"Low Risk" (< 4) or "High Risk" (>= 4).

Recommendation

Clinical guidance for monitoring.
